Muscle soreness is felt the day after more often than the day of a workout. If a person has a workout in the morning they may feel tired or fatigued in the region they worked in the morning but it usually isn’t sore. The soreness kicks in the day or 2 afterwards. Why is that? Why isn’t it sore the day of later on?
In: Biology
Soreness is caused by the repair process, which doesn’t kick in until a day or so later. Your body “knows” that healing is best done when the stress event is over, so there is a day or so of lag to ensure that you’ve past the period where you _need_ the muscles and are more likely to be in a period where repair can be optimal.
That is also why it hurts to push sore muscles – your body is trying to get you to take it easy to the repair process can finish.
